This is the first guitar version of the 3D bridge by Schaller I've owned after buying two bass versions and I wouldn't buy another bridge ever again.
I used the 3D-6 chrome bridge on a custom Tele-style guitar with two humbuckers. I've had some Fender Telecasters before and I've hated the Fender bridges with their very limited adjusting so I wanted something different for my custom build and the Schaller 3D-6 is just what I'd been looking for. Before I used to hate setting the intonation, but with the 3D-6 it's extremely easy as the bridge comes with good instructions on how to set up the bridge.
If you're replacing a Fender bridge or similar you might have to do some tweaking because the holes might not be 100% accurate, but if you use the bridge on a custom build it won't be a problem.
Overall, the 3D-6 is the best guitar bridge I've ever come across, and I will be buying more of these to replace factory bridges on my other guitars. Try one and you'll fall in love.
